To-(LZZ whoml t may concern:

Be it known that I, CARL A. MA'rsoN, a

citizen of the United States, residing at.

Swampscott, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in Lace-Tipping Machines, of :which the following is a specification.

This invention relates to a lace tipping machine. The object of the invention is to provide a machine for forming metal tips uponl Shoe laces or the like and securely fastening said tips to said laces.

It is also an object of the invention to provide a' novel mechanism for clamping the lacing, and while thus clamped feeding said lacing transversely `into position to have the metal tip rolled therearound by the tip forming instrumentalities, provision being made for automatically preventing the strip of sheet metal, from which the tip is formed, from being fed and a piece cut therefrom if the lacing is not in position to receive the tip. A

It is still further an object of the invention to provide means for simultaneously feeding and corrugating the strip of sheet material from which the tip is formed and for giving the corrugations thus formed a final pressing prior to the operation of l forming the tip'.

The invention consists in the combination and arrangement of parts whereby the above objects' and cer-tain other objects hereinafter appearing may be obtained as set forth in the following specification and particularly pointed out in the claims thereof.

., Referring to the drawings:

Like numerals refer to like parts throughout the several views ofthe drawings.

In the .drawings 1 represents the frame of the machine upon which is supported in suitable bearings 2 a driving shaft 3 which is driven by a pulley 4. Fast to the shaft 3 is an eccentric 5 which is adapted to impart a reciprocatory motion vto a horizontal slide 6 to which it is operatively connected by an eccentric strap 7, rod 8 and member 9, the said member 9 being secured'to the slide 6 by a pin 10. The slide 6 is arranged to slide in Asuitable ways 11 provided in the frame 1,

and the position of said slide may be adjusted for purposes hereinafter appearing by means of the rod 8, which is provided with` right and left hand screw-threaded portions having engagement with the membcr 9 and eccentric strap 7 respectively. The rod 8 when properly adjusted is locked to the member 9 and strap. 6 by lock-nuts 12 and 13 respectively.

A strip of sheet material 14 from which the tips are formed is fed vertically into a from the` slide 6 is a cam 16 vwhich is adwith is a feed roll 33 around the periphery.

justably secured to said lug` by a bolt 17 which passes through a slot 18 provided in the cam. The working cam surface is composed ofan inclined edge 19 and a horizontally disposed edge 20, the said edge 20 con-k stituting a rest. A cam roll 21 is rotatably mounted upon a cam arm 22, one end of which is pivotally/attached to a stud 23 projecting from the frame 1. Av spring 24 acts to always hold the cam roll 21 against the 'working surface of. the cam 16. The outer end o f the cam arm 22 is provided with a slot 25 through which extends 'a stud 26 which is adjustably mounted in a slot 27 provided in'an arm 28 pivoted upon a'shaft 29 adapted to rotate in the frame 1. A pawl 30 carried by the arm 28 is forced by a spring 31 into engagement with a ratchet 32 fast to the shaft 28 and the rocking move` ment imparted to the arm 28 by the arm 22 and cam 16 feeds the ratchet 32 a predetermined number of teeth with each forward movement of the reciprocatory slide 6. The number of teeth engaged by the pawl 30 with'each rocking movement of the arm 28 maybe varied by adjusting the location of the stud 26 upon the arm 28.

Fast to the shaft 29 and rotatable thereof which extends two sets of equally spaced corrugations 34 between the sets of which is located an uncorrugated surface 35. Fast to the-feed roll 33 is a spur gear 36 which meshes with and drives another spur gear 37 fast to another feed roll 38 around the periphery of which also extends two sets of corrugations 39, between the sets of which islocated an uncorrugated surface 40. The corrugations 39 are adapted to co-operate with the corrugations 34 to form corrugations 41 in the sheet material 14 as it passes between the feed rolls 33 and 38 while the un'orrugated surfaces 35 and 40 will leave an uncorrugated surface 42 upon said strip as illustrated in Fig. 7 The feed roll 38 is rotatably mounted upon a shaft 43 supported in a pair of arms 44 forming a part of a lever 45 which is pivoted to rock upon a shaft 46 supported in the frame 1.

An arm 47 forming a part of the lever 45 is located upon the opposite side o-f the shaft 46 from the arms 44 and said arm .47 is provided with an adjusting screw 48 which extends therethrough having a shoulder formed thereon, and between said shoulder land a portion of the frame 1 is located a spring 49 which acts to force the feed roll 38 against the strip of sheet material 14 and press said material between the rolls 38 and 33- simultaneously with the feeding of said material by saidrolls.

'Ifo facilitate the presentation of material. A,`whi`ch comprises the lacing, to the worksupport where the tip is lattached thereto, means are provided vfor 'clamping said material, and while thus clamped, feeding it transversely thereof into position upon'the work-support as follows: Fastened by the bolt 17 to the opposite side of the lug 15 from that to which the cam 16 is attached is an angle-bar 5() to which is adjustably attached by nuts 51 a rod 52. The rod 52 has rack teeth 53 formed upon the outer portion thereof which mesh with and drive a gear 54 loosely mounted upon a shaft 55 supported in the frame 1, see Fig. 4. A lu 56 is formed integral with the gear 54 an to this lug is pivoted at 57 a pawl 58 which 4engages a ratchet 59 fast to the shaft 55.

`therein a main body portion 62 and side plate 63 between which are pivotally mounted upon pins 64 a plurality of clamping members 65. A stationary cam 66 is located upon each side of the frame 1 being attached to said frame.' The inner ends of the clamping members 65 arerounded at 67 and said ends are forced bylplungers 68 and springs 69 against vthe working surface of the cam 66. The outer ends 70of`the clamping members ,65 provide a means for first hooking the lacing A to the rotary member 61, and finall clamping said lacing to said rotary mem er, at which time the ends 70 co-operate with recesses`71 formed in the periphery of the main body portion 62 to securely grip the lacing A.

In preparing the lacing A for presentation to the lacing feeding'instrumcntalities, the said lacing vwhich is of indefinite length vis arranged in coils as illustrated in Fig. 14 in which one coil only is shown and portions a of said coils Vare placed manually .by operatives one at a time upon the rotary feeding members 61 behind the outer ends 70 of the clamping members 65 as illustrated in Fig. 1. As the feeding members 61 are rotated. the lacing A is automatically clamped by the clamping members 65 and the lacing eventually is deposited upon a block which constitutes a work-support 72 in front Ief and against a pair of positioning pins 7 3 as illustrated in Figs. 2 and 6 which project upwardly from the work-support. During the intervalthat the lacing rests upon thework-support it is yieldingly held by the clamping means 65 upon opposite sides of the work-support.

ln order that the sheet material 14 may be perfectly corrugated', auxiliary corrugating means are provided to press said material subsequently to its passage between the feed rolls 33 and 38. This final corrugating operation is accomplished as follows: Attached to the under surface of the reciprocatory slide 6 is a block 74 which constitutes the movable member of the auxiliary corrugating means; The block 74 is adjustably attached to the slide 6 by a screw 7 5 which passes through a slot 76 provided in said block. The forward edge of the block 74 is provided with two sets of equally spaced corrugations 77 between the sets of which is an uncorrugated surface 78, see Fig. 9. Formed upon the rear edge of the worksupport 72 are two sets of corrugations 79 between the sets of which is an uncorrugated surface 80, see Fig. 8. rlhe corrugations 77 and 79 are identical in formation with the corrugations 34 and 39 of the feed rolls 33 and 38. The block 74 is so positioned relatively to the work-support 72 that with each forward movement of the slide 6, the corrugations 77 of the auxiliary corrugating means will co-operate with the corrugations 79 of the work-support 72 as illustrated in Fig. 12 to perform a final pressing operation upon the corrugations 41 already formed in the strip of sheet material 14.

The instrumentalities for severing a piece of material from the strip 14 and rollingv` said piece around the lacing A are as follows: Fastened to the reciprocatory slide 6 is a member 81 which is provided with a cutting edge 82 which is adapted to cooperate with a cutting edge 83 provided upon the work-support 72. The member 81 is furthermore provided with a tip forming recess 84 having a semi-circular rear wall 85 which intersects the cutting edge 83. The member 81 constitutes a movable tip forming member. A stationary tip forming member 86 abuts against the work-support 72 and is provided with a semi-circular tip forming recess 87. The work-support 72 and stationary tip forming member 86 each rest upon a horizontal portion of the frame 1, and are simultaneously clamped against a vertical portion of said frame by a pair of clamping screws 88, see Figs. 3 and 6. As the reciprocatorv slide 6 moves forward, the front edge of the tip forming member "u 81 first contacts with the upper end of the strip of sheet material 14 as illustrated in Fig. 3, bending said material and folding it so as to rest upon the lacing A as illustratedl in Fig. 10. rlhe cutting edges 82'and 83 then co-operate to sever a piece of material 89 from the strip 14 as illustrated in Fig. 11, and finally the upper wall of the recess 84, curved rear wall 85 of said recess, curved recess 87 and upper flat surface of the worksupport 72 all co-operate to roll the piece rotary lacing feeding members 61 fail to.

deposit the lacing A upon the Work-support 72 it is desirable that there shall not be a piece of material 89 severed from the strip 14, thereby preventing waste of lsaid material 14 and also preventing an unused piece of said material from clogging the tipl forming instrumentalities. Means are, therefore, pro

vided for preventing the strip of sheet material 14 from being fed if the lacing'is not clamped to the lacing feeding members 61. Pivotally mounted upon the frame 1 at 90 in a. position to be engaged by the lacing A just prior to being deposited upon the worksupport 72, is a lever 91, the norma-l position of which is illustrated in dotted lines in Fig. 1. A flat spring 92 engages the under side of the lever 91 and acts to always force said lever upwardly. The lever 91 is operatively connected with a vertical pin 93 which, when in` its lowered position, projects in the path of an arm 94 which is pivoted at 95 to the frame 1. A link 96 connects the arm 94 with the shaft 43 upon which the feed roll 38 is mounted. Fast to the shaft in vertical alignment with the arm 94 is a member 97 which is provided with a plurality of raised portions 98 formed upon the periphery thereof which are adapted to Contact with a projection 99 formed upon the arm 94 and intermittently rock said arm a sufficient distance to allow the pin 93 to drop in the path of the upper end of the arm 94. The number of raised portions 98 correspond to the number of clamping members and with each intermittent movement of the rotary lacing feeding members 61, the arm 94 will be rocked, thereby pulling the feed roll 38 Yout of engagement with the strip of sheet material 14 and permitting the pin 93 to fall behind the upper end of the arm 94 thereby relieving the pressure upon the material 14. As long as there is no lacing A present upon the lacing feeding mem.- bers 61, the strip of material 14 will fail to feed, but when said lacing is clamped in position, the said lacing will engage the lever 91 forcing the long arm thereof downwardly and thereby raising the pin 93 from behind the arm 94 and again allowing the spring 49 vto force the feed roll 38 against the strip of material 14 thereby allowing said material to feed.

llO

, screws 102, sec Figs. 2 and l During such times as the feed roll 38 is -removed from engagement with the strip of sheet material 14, the said strip is prevented from drop-ping by a friction device consist- 1 ing of a. layer of compressible material 100,

such as felt or the like a plate 101` and 3, there being 'just enough pressure placed upon the strip of sheet material 14 by the screws 102 to prevent the said sheet material from dropping when notheld by the feed rolls, yet allowing said sheet material to easily be fed between the material 100 and a flat surface L been rolled around the lacing A means are provided which are actuated by the reciprocatory slide 6 for severing said lacing and vthe material located therearound as follows:

Extending through the work-support 72 is l an opening 104, the upper edge of which constitutes a stationary cutter. The upper sur face of the work-support is also provided with av shallow recess 105 which intersectsk the openingt103 and is so located that the lacing Av will align therewith when in position upon the W'ork-supp0rt- 106 is a. cutter blade 107 which is provided with a V-shaped cutting edge 108. The cutter blade 107 constitutes the movable member of the lacing severing instrumentalities. The slide 106 is adapt-ed to reciprocate in a. vertical bearing 109 provided inthe frame 1,land is4 connectedby a link 110 with a leyer 111 which is pivoted Aat 112 between a pair of cars 113. A link 114 is attached by pins 115 and 116 to the lever 111 and the reciprocatory slide 6 respectively. During the forward movement of the reciprocatory slide 6 and the operation of the tip forming instrumentalities, the movable cutter 107 is moving upwardly as illustrated in Figs. 10, 11 and 12. When, however, the slide 6 moves rearwardly, the movable cutter descends and the lacing A which at the completiony of the operation of attaching the tip is positioned as illustrated in Fig. 12 also moves rearwardly because of its own elasticity until it is lagain positioned as illustrated in Fig. 3. The

l downward movement of the movable cutter is so timed tha as soon as the tip `forming member 81 is vfithdrawn, as illustrated in Fig. 13 the cutter 107 will contact with the piece of material 89 midway of the uncorrugated surface 42 and sever said' material and the lacing therein upon the line as illustrated in Fig. 14 and the material thus severed will constitute tips for one end 'of two separate laces.

The general operation of the machine Supported 1 above the work-support in a vertical slide brieiy described is asfollows: The lacing AA rests upon a suitable table, not shown inthe drawings, in front of the machine with the line b, Fig. 14, in alignment with the center line of the machine. The portions @of the coils of lacing are then placed one at a time by an operative upon .the lacing feedin members 61 behind the outer end 70 of eac clamping member 65 fand as said` lacin feeding members areA intermittently" rotate the lacing is Vclamped by the clamping members 65 to the ,members 61. The normal position of the lever 91 is as illustrated in dotted lines Fig. 1, at which time the feed roll 38 isheld out of engagement with the strip of sheet material 14. As the lacing feeding members 61 rotate, the lacing clamped thereon will engage the lever 91 forcing the long arm thereof downwardly lifting the pin 93 and releasing the arm 94, whereupon the feed roll 38`will be forced against the stri of sheet material by the spring 49. The acing A is deposited by the lacing feeding members upon the work-support 72 toward the end of the rearward movement of the reciprocatory slide 6 and immediately thereafter with the first portion of the next forward movement of the reciprocatory slide 6, the strip of sheet material 14 is fed upwardly by the feed wheels 33 and 38, which also act to corrugate said strip simultaneously with the feeding operation. If the operative neglects to place the lacing in position .upon the lacing feeding members 61, when that portion of said members arrives in the position where the lever 91 should be engaged by the lacing if it were present, the lever 91 will not be moved and .the feed roll 38 being out of contact with the strip of sheet material 14, will fail to feed said material. ging of the tip forming instrumentalities by preyenting a'tip from being formed if there is no lacing present to receive saidtip. Im-

mediately following the feeding operation of the strip of sheet material 14, the member 81 of the tip forming instrumentalities will engage the upper end of the strip 14 bending it upon the lacing A which is resting upon the work-support and while thus bent, isl

severed from the rest of the strip and rolled around the lacing. Simultaneously Y with this operation at the very end of the forward movement of the slide 6 the auxiliary corrugating instrumentalities will perform a final corrugating operation upon the strip of material 14 which has previouslybeen corrugated by the feed rolls 33 and 38. After the tip has been formed around the lacing, the material comprising said tip is severed midway of the uncorrugated surface 42 thereof and the severed portions of said material thereafter constitute tips for the ends of the completed lace as illustrated in Fig. 15.

This will prevent any clog- The corrugations 'are so formedin the sheet material that they will securely grip the lacing and prevent the tips from being pulled from the ends of the completed lace. It is evident that the corrugations may be eliminated from the feed rolls and the corrugating operation performed entirely by the auxiliary corrugating means, or the auxiliary corrugating means may be eliminated and the corrugating operatlon entirely performed by the feed rolls if it is so desired. It .is also evident'that in place of the corrugations illustrated other forms of scoring the strip of sheet material may be employed Without departing from the spirit of this invention as, for example, punching indentations therein in order that the said material may grip the lace to prevent the tip from accidentally slipping from the endY thereof.

It should be distinctly understood that the term lacing as used in this specification and in the claims which follow designates the material of which the finished laces are composed.

While it is preferable to provide a mechanism for clamping the lacing and feeding the same upon the Work-support, it will be evident that this feeding and clamping mechanism may be entirely eliminated and the lacing fed by hand upon the Work-support 72 without ,departing from the spirit of this invention.

At such times the lacing A is grasped by the operator with both hands and While pulled tight is placed upon the Work-support 72 against the pins 73, the said lacing engaging the lever 91 as the lacing approaches the Work-support as previously described, and allowing the strip of sheet material 14 to feed in the usual manner. Aside from the elimination of the feeding members 6l and the clamping instrumentalities thereon, the entire mechanism and operation of the same is exactly the same as has previously been described.

My present machine is capable of applying any desired material in sheet form to laces, Whether said tipping material is metal, metallic alloy, celluloid or other material, even though the material will afterward be capable of melting and fusing With the lace, so long as it can be handled by the feeding devices, cut by the die and be set about the lace, and irrespective of Whether the laces be round, tubular or flat.
